The Ginger Ninjas are a rock group touring on Yuba Mundo cargo bikes. They’re using nothing but human-power for both transport and amplification for the entire tour. From the press release:
What does a truly sustainable music tour look like? The Ginger Ninjas rock and roll band will be on tour using Mundo Bikes made by Yuba Bicycles to travel from city to city unsupported by fossil-fuelled vehicles and playing on a stage that is totally bicycle powered. Called “Bicycle Music Festivals”, the band’s Pleasant Revolution World Tour includes stops in the US and Europe.
